Abstract

The objective of this research is to determine a robust method for designing shock and vibration laboratory test fixtures that accurately reproduce the field environment for the component of interest. The methods presented in this research examine the boundary conditions presented unto the component of interest through transfer path analysis with the intent of reproducing the next-structure attachment impedance with a laboratory test fixture of one and two attachments. The first method includes only using the next-structure relative motion and stiffness to design a test fixture, while the second method uses an optimization algorithm to develop a lumped parameter model that produces equivalent attachment FRFs. Both methods are conducted and validated using the Box Assembly with Removable Component structure with two attachment locations fashioned by the Department of Energy’s Kansas City National Security Campus, operated and managed by Honeywell Federal Manufacturing & Technologies, LLC and Sandia National Laboratories.
